2. General Information
2.1 On-Board Diagnostics (OBD)
The first generation of On-Board Diagnostics (called OBD I) was
developed by the California Air Resources Board (CARB) and
implemented in 1988 to monitor some of the emission control
components on vehicles. As technology evolved and the desire to
improve the On-Board Diagnostic system increased, a new generation of
On-Board Diagnostic system was developed. This second generation of
On-Board Diagnostic regulations is called "OBDII".
The European version of OBDII is commonly referred to as EOBD and
has protocols developed for the European vehicle market.
The EOBD system is designed to monitor emission control systems
and key engine components by performing either continuous or
periodic tests of specific components and vehicle conditions. When a
problem is detected, the EOBD system turns on a warning lamp (MIL)
on the vehicle instrument panel to alert the driver typically by the
phrase of “Check Engine” or “Service Engine Soon”. The system will
also store important information about the detected malfunction so that
a technician can accurately find and fix the problem.

3.
Whether the Malfunction Indicator Light (MIL) is
commanded 'on' or 'off';
Which, if any, Diagnostic Trouble Codes (DTCs) are stored;
Readiness Monitor status.
2.2 Diagnostic Trouble Codes (DTCs)
EOBD Diagnostic Trouble Codes are codes that are stored by the
on-board computer diagnostic system in response to a problem found
in the vehicle. These codes identify a particular problem area and are
intended to provide you with a guide as to where a fault might be
occurring within a vehicle. EOBD Diagnostic Trouble Codes consist of
a five-digit alphanumeric code. The first character, a letter, identifies
which control system sets the code. The other four characters, all
numbers, provide additional information on where the DTC originated
and the operating conditions that caused it to set. On the next page is an
example to illustrate the structure of the digits:

2.3 Location of the Data Link Connector (DLC)
The DLC (Data Link Connector or Diagnostic Link Connector) is the
standardized 16-cavity connector where diagnostic code readers
interface with the vehicle's on-board computer. The DLC is usually
located 12 inches from the ENTER/EXIT of the instrument panel
(dash), under or around the driver’s side for most vehicles. If Data Link
Connector is not located under dashboard, a label should be there
telling location. For some Asian and European vehicles, the DLC is
located behind the ashtray and the ashtray must be removed to access
the connector. If the DLC cannot be found, refer to the vehicle’s
service manual for the location.
VS8702 _ 1.0 _ 30/06/09

Figure 1-1: The DLC connector (left) can be found in the area of
the car interior seen at right (black arrow).
2.4 OBDII Readiness Monitors
An important part of a vehicle’s OBDII system is the Readiness
Monitors, which are indicators used to find out if all of the emissions
components have been evaluated by the OBDII system. They are
running periodic tests on specific systems and components to ensure
that they are performing within allowable limits.
Currently, there are eleven OBDII Readiness Monitors (or I/M
Monitors) defined by the U.S. Environmental Protection Agency
(EPA). Not all monitors are supported by all vehicles and the exact
number of monitors in any vehicle depends on the motor vehicle
manufacturer’s emissions control strategy.
Continuous Monitors -- Some of the vehicle components or systems are
continuously tested by the vehicle’s EOBD system, while others are tested
only under specific vehicle operating conditions. The continuously
monitored components listed below are always “OK” ready: Once the
vehicle is running, the EOBD system is continuously checking the
individual components, monitoring key engine sensors, watching for
engine misfire, and monitoring fuel demands. These continuous monitors
are:
1 ) Misfire monitoring - detects abnormal variations in the
crankshaft velocity.
2) Fuel System - monitors air/fuel ratio to ensure maximum fuel
efficiency.
VS8702 _ 1.0 _ 30/06/09
4
3 ) Comprehensive Components (CCM) - monitors individual
sensors and actuators.
Non-Continuous Monitors -- Unlike the continuous monitors, many
emissions and engine system components use multiple sensors to ensure the
integrity of each system listed below. These system monitors require the
vehicle to be operated under specific conditions (engine speed, coolant
temperature, duration of drive etc.) before the monitor is ready to be tested.
These monitors are termed non-continuous monitors and are listed below:
1. EGR System - Exhaust Gas Recirculation for reducing greenhouse
gases.
2. O2 Sensors - Used to monitor and adjust air/fuel mixture.
3. Catalyst - Used to reduce exhaust emissions.
4. Evaporative System - Used to monitor the integrity of fuel tank
system.
5. O2 Sensor Heater - Brings 02 sensor to correct operating
temperature.
6. Secondary air - Used to reduce exhaust emissions.
7. Heated Catalyst - Brings catalyst to correct operating
temperature.
8. A/C system - monitors system for Freon leaks.
2.5 EOBD Monitor Readiness Status
EOBD systems must indicate whether or not the vehicle’s PCM’s
monitor system has completed testing on each component.
Components that have been tested will be reported as “Ready”, or
“Complete”, meaning they have been tested by the EOBD system. The
purpose of recording readiness status is to allow inspectors to
determine if the vehicle’s EOBD system has tested all the components
and/or systems.
The powertrain control module (PCM) sets a monitor to “Ready” or
“Complete” after an appropriate drive cycle has been performed. The
drive cycle that enables a monitor and sets readiness codes to “Ready”
varies for each individual monitor. Once a monitor is set as “Ready” or
“Complete”, it will remain in this state. A number of factors, including
erasing of diagnostic trouble codes (DTCs) with a code reader or a
disconnected battery, can result in Readiness Monitors being set to
“Not Ready”. Since the three continuous monitors are constantly
evaluating, they will be reported as “Ready” all of the time. If testing of
VS8702 _ 1.0 _ 30/06/09
5
a particular supported non-continuous monitor has not been
completed, the monitor status will be reported as “Incomplete” or “Not
Ready.”
In order for the EOBD monitor system to become ready, the vehicle
should be driven under a variety of normal operating conditions. These
operating conditions may include a mix of highway driving and stop
and go, city type driving, and at least one overnight-off period. For
specific information on getting your vehicle’s EOBD monitor system
ready, please consult your vehicle owner’s manual.
2.6 EOBD Definitions
Powertrain Control Module (PCM) -- EOBD terminology for the
on-board computer that controls engine and drive train.
Malfunction Indicator Light (MIL) -- Malfunction Indicator Light
(Service Engine Soon, Check Engine) is a term used for the light on the
instrument panel. It is to alert the driver and/or the repair technician
that there is a problem with one or more of vehicle's systems and may
cause emissions to exceed federal standards. If the MIL illuminates
with a steady light, it indicates that a problem has been detected and the
vehicle should be serviced as soon as possible. Under certain
conditions, the dashboard light will blink or flash. This indicates a
severe problem and flashing is intended to discourage vehicle
operation. The vehicle onboard diagnostic system can not turn the MIL
off until the necessary repairs are completed or the condition no longer
exists.
DTC -- Diagnostic Trouble Codes (DTC) that identify which section
of the emission control system has malfunctioned.
Enabling Criteria -- Also termed Enabling Conditions. They are the
vehicle-specific events or conditions that must occur within the engine
before the various monitors will set, or run. Some monitors require
the vehicle to follow a prescribed “drive cycle” routine as part of the
enabling criteria. Drive cycles vary among vehicles and for each
monitor in any particular vehicle.
EOBD Drive Cycle -- A specific mode of vehicle operation that
provides conditions required to set all the readiness monitors
VS8702 _ 1.0 _ 30/06/09
6
applicable to the vehicle to the “ready” condition. The purpose of
completing an EOBD drive cycle is to force the vehicle to run its
onboard diagnostics. Some form of a drive cycle needs to be performed
after DTCs have been erased from the PCM’s memory or after the
battery has been disconnected. Running through a vehicle’s complete
drive cycle will “set” the readiness monitors so that future faults can be
detected. Drive cycles vary depending on the vehicle and the monitor
that needs to be reset. For vehicle specific drive cycle, consult the
vehicle’s Owner’s Manual.
Freeze Frame Data -- When an emissions related fault occurs, the
EOBD system not only sets a code but also records a snapshot of the
vehicle operating parameters to help in identifying the problem. This
set of values is referred to as Freeze Frame Data and may include
important engine parameters such as engine RPM, vehicle speed, air
flow, engine load, fuel pressure, fuel trim value, engine coolant
temperature, ignition timing advance, or closed loop status.
2.7 EOBD II Modes of Operation
Here is a basic introduction to the EOBD communication protocol.
Mode byte: The first byte in the stream is the mode number. There are 9
modes for diagnostic requests, so this first byte is from 1 to 9. The first
byte in the response data bytes is this same number plus 64. For example, a
mode 1 request would have the first data byte = 1, and the response would
have the first data byte
= 65. Here is a brief description of the modes:
Mode $01 - Identifies the Powertrain information and shows current
data available to the scan tool. This data includes: DTCs set, status of
on-board tests, and vehicle data such as engine RPM, temperatures,
ignition advance, speed, air flow rates, and closed loop status for fuel
system.
Mode $02 - Displays Freeze Frame data. Same data as in mode 1, but it
was captured and stored when a malfunction occurred and a DTC was set.
Some of the PIDs for mode one are not implemented in this mode.
Mode $03 - Displays the type of powertrain or emission related DTCs
stored by a 5 digit code identifying the faults. There may be more than
one response message if there are more trouble codes than will fit in the
data bytes of the response message, or if there are more than one ECU
computer responding.
VS8702 _ 1.0 _ 30/06/09
7
Mode $04 - Used to clear DTCs and Freeze Frame data. This clears all
diagnostic trouble codes that may be set including freeze frame data and
readiness monitors.
Mode $05 - Oxygen Sensor Test Results. This mode displays the oxygen
sensor monitor screen and the test results gathered about the oxygen
sensor.
There are ten numbers available for diagnostics:
1. $01 Rich-to-Lean O2 sensor threshold voltage
2. $02 Lean-to-Rich O2 sensor threshold voltage
3. $03 Low sensor voltage threshold for switch time measurement
4. $04 High sensor voltage threshold for switch time measurement
5. $05 Rich-to-Lean switch time in ms
6. $06 Lean-to Rich switch time in ms
7. $07 Minimum voltage for test
8. $08 Maximum voltage for test
9. $09 Time between voltage transitions in ms
Mode $06 - Non-Continuously Monitored Systems test results. There
are typically a minimum value, a maximum value, and a current value for
each non-continuous monitor. This data is optional, and it is defined by a
given vehicle maker if it’s used.
Mode $07 - Request for DTCs (pending) from Continuously
Monitored Systems after a single driving cycle has been performed to
determine if repair has fixed a problem. This is used by service
technicians to verify repair was performed properly and after clearing
diagnostic trouble codes.
Mode $08 - This Special Control Mode requests control of the
on-board system, test, or component bi-directionally (where
applicable). This mode is manufacturer specific.
Mode $09 - Reports vehicle information. This information includes
vehicle VIN number and calibration information stored in the vehicle
ECUs.

3.7 Vehicle Coverage
The VS87002 OBDII/EOBD Code Reader is specially designed to
work with all EOBD compliant vehicles, including those equipped with
the next-generation protocol -- Control Area Network (CAN).
A small number of 1994 and 1995 model year petrol vehicles are
OBD11/EOBD compliant. Government regulations mandate that all
EOBD compliant vehicles must have a “common” sixteen-pin Data
Link Connector (DLC).
For your vehicle to be EOBD compliant it must have a 16-pin DLC
(Data Link Connector) under the dash.

4.5 Retrieving I/M Readiness Status
I/M Readiness function is used to check individual Emission
System readiness tests on OBDII compliant vehicles. It is an
excellent function to use prior to having a vehicle inspected for
compliance to a state emissions program. CAUTION - by clearing
trouble codes you also clear the readiness status for the individual
emission system readiness tests. In order to reset these monitors,
the vehicle must be driven through a complete drive cycle with no
trouble codes in memory. Times for reset vary depending on
vehicle.
Some latest vehicle models may support two types of I/M Readiness
tests:
VS8702 _ 1.0 _ 30/06/09
23
A.
B.
Since DTCs Cleared - indicates status of the monitors since the
DTCs are erased.
This Drive Cycle - indicates status of monitors since the
beginning of the current drive cycle.
An I/M Readiness Status result of “INC” does not necessarily
indicate that the vehicle being tested will fail the state I/M
inspection. For some states, one or more such monitors may
be allowed to be “Not Ready” to pass the emissions
inspection.
- “OK” -- Indicates that a particular monitor being checked has
completed its diagnostic testing.
- “INC” -- Indicates that the testing of a particular monitor being
tested is incomplete. Additional driving is needed.
- “N/A” -- The monitor is not supported on that vehicle.
1) Use SCROLL button to select I/M Readiness from Diagnostic
Menu and press ENTER/EXIT.
